title: [Placenta accreta--prenatal diagnosis, treatment].
abstract: Placenta accreta is a potentially life threatening obstetric condition that requires a multidisciplinary management. Placenta praevia and previous Cesarean section are the two most important known risk factors for placenta accreta. This study presents two patients having both of the foremention risk factors diagnosed ultrasonographically with placenta accreta in the second trimester. Ultrasound findings considered suggestive of placenta accreta are: presence of placental lacunae (vascular spaces), loss of the hyperehoic uterine serosa-bladder wall interface, loss of the retroplacental hypoechoic clear space, hypervascularity of the interface between the uterine wall and the bladder wall/isthmico-cervical zone, presence of placenta praevia, either anterior or posterior, overlying the uterine scar. Both of the cases with suspected placenta accreta ended successfully by planned preterm Cesarean hysterectomy with the placenta left in situ. Placenta accreta is a significant cause of maternal morbidity and mortality and the most common reason for urgent postpartum hysterectomy.
